Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Interventions will include posture change (supine position) and hand gripping (squeezing stress ball in the opposing arm to the venous cannulation). There will be three interventional groups:
1, Patient will assume supine position during PIVC (peripheral intravenous cannulation), patient will remain flat until either the patient requests to sit upright or is transferred to the CT scanner.
2, Patient will be in sitting position and squeeze a stress ball in opposing arm to the insertion of PIVC until the PIVC is secured.
3. Patient will assume supine position during the PIVC insertion, the patient will remain flat until either the patient requests to sit upright or is transferred to the CT scanner. Meanwhile Patient will be instructed to squeeze a stress ball in opposing arm to the insertion of PIVC until the PIVC is secured.
The interventions will continue until successful insertion of the PIVC. The primary nurse will be administering the relevant intervention under direct supervision of the research staff. Training will be provided to ensure all nursing staff in the Imaging department perform their tasks uniformly. Research staff will be always available onsite to provide supervision and monitor adherence to the interventions.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Block and stratified randomization will be performed by a person who is not associated with the study using computer generated sets of random allocations. Assignments will be concealed in a consecutively numbered opaque envelope and kept in a locked cabinet.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block and stratified randomization: using online software for random sequence generation, block size of 4 and 8, and age ( under 50 or 50 or over) as stratification factor.

Summary
Brief summary
This study is a randomized controlled trial, testing preventative/treatment strategies for managing vasovagal responses induced by intravenous cannulation in patients requiring cardiac CT with contrast. The strategies involve the employment of counter pressure maneuvers (hand gripping and/or adopting a lying down position) during intravenous cannulation.
The researcher hypothesizes that the employment of counter pressure maneuvers (hand gripping and/or adopting a lying down position) will decrease the incidence of vasovagal response induced by intravenous cannulation.
